Truthear Gate

Manufacturer: Truthear

The Truthear Gate is an in-ear monitor centered around a single dynamic driver configuration, housed in a shell constructed through a 3D-printed resin process. It carries a straightforward, no-frills design without a built-in microphone, in-line controls, or a bundled travel case, keeping the focus squarely on the listening experience.

On the technical side, the Gate uses a composite diaphragm and operates within a standard 20 Hz to 20,000 Hz frequency range, with an impedance of 28 ohms and a total harmonic distortion rated at ≤1% measured at 1 kHz and 94 dB. It connects via a 3.5 mm connector and ships with a 1.2-meter oxygen-free copper cable attached through a fixed 2-pin (0.78 mm) connection, meaning the cable is not detachable.

Pros
  • The composite diaphragm dynamic driver covers the full 20 Hz to 20,000 Hz frequency range, spanning the entire audible spectrum
  • Total harmonic distortion is rated at 1% or below at 1 kHz and 94 dB, indicating low signal coloration at that measured point
  • The 28-ohm impedance is moderate and does not require specialized amplification equipment to drive
  • The oxygen-free copper cable is a higher-purity conductor material compared to standard copper alternatives
  • The 3D-printed resin shell construction allows for a precise and consistent form factor
Cons
  • The cable is not detachable, so any damage to it cannot be resolved by simply swapping in a replacement
  • No in-line control panel is included, meaning playback and volume adjustments must be handled at the source device
  • There is no built-in microphone, limiting hands-free use for calls or voice input
  • No travel bag is bundled in the package, leaving the user without a dedicated storage or carrying solution
  • The single dynamic driver configuration offers no multi-driver setup, which limits acoustic tuning flexibility
Who is this for?

The Truthear Gate is well suited to listeners who prefer a straightforward, single-driver in-ear monitor for everyday personal audio use. Its 28-ohm impedance means it can be driven directly from a smartphone, laptop, or portable media player without requiring dedicated amplification. The full 20 Hz to 20,000 Hz frequency range and low THD rating make it a reasonable choice for general music listening where a clean, uncolored signal is valued. The fixed 3.5 mm connection also suits users who rely on devices with a standard headphone output.

Who is this NOT for?

Users who frequently damage or wish to customize their cables will find the non-detachable cable a significant limitation, as it cannot be replaced without affecting the entire unit. Those who need hands-free calling or voice assistant access on the go will be hindered by the absence of both a built-in microphone and an in-line control panel. Additionally, the single dynamic driver setup offers no layered acoustic tuning, making this a poor fit for listeners who specifically seek the kind of sound staging or frequency separation that multi-driver configurations can provide.

General info:

Driver configuration 1DD
Type of drivers Dynamic driver (DD)
Diaphragm material Composite
Shell material/process 3D-printed resin
has a built-in microphone ✕
travel bag is included ✕
Has an in-line control panel ✕

The Truthear Gate uses a single dynamic driver (1DD) configuration, with a composite diaphragm handling sound reproduction across the full frequency range. Its shell is formed through a 3D-printed resin process, lending a precise and consistent build. The unit does not include a built-in microphone, an in-line control panel, or a travel bag.

Specifications:

drivers count 1
impedance 28 Ohms
Total harmonic distortion (THD) ≤1% (@1kHz, 94dB)
lowest frequency 20 Hz
highest frequency 20000 Hz

The Truthear Gate is built around a single driver and carries an impedance of 28 ohms, making it relatively straightforward to drive. Its frequency response spans from 20 Hz to 20,000 Hz, covering the full range of human hearing. Total harmonic distortion is rated at ≤1% measured at 1 kHz and 94 dB, indicating a low level of signal coloration under those conditions.

Cable:

Connector type 3.5 mm
Pin connector 2-Pin (0.78 mm)
Cable material Oxygen-free copper (OFC)
cable length 1.2 m
has a detachable cable ✕

The included cable is made from oxygen-free copper (OFC) and measures 1.2 meters in length, terminating in a standard 3.5 mm connector. It attaches to the earphones via a 2-pin (0.78 mm) interface, though it is worth noting that the cable is not detachable, meaning it cannot be swapped out for an aftermarket alternative.

Final Verdict

The Truthear Gate is a no-frills single dynamic driver in-ear monitor that delivers on the basics — a full audible frequency range, low harmonic distortion, and a moderate impedance that pairs naturally with everyday source devices. Its fixed oxygen-free copper cable and 3D-printed resin shell reflect a straightforward build approach, which works well for casual daily listening but leaves little room for customization or feature expansion. Users looking for a microphone, swappable cables, or multi-driver acoustics will need to look elsewhere, but for those whose needs align with its focused feature set, the Gate presents a clean and uncomplicated listening tool.
